I once had an elderly Japanese patient who loved to make jokes and have the nurses rolling in laughter all the time. While doing his A.M. care one day, I said to him: Mr. Watanabe, how do I get rid of geckos? He said, "Buy an Iguana!" Then, he laughed that infamous laugh of his while I died laughing. Loved that patient! He no doubt has passed on into a better life by now since he was pretty close to 90 in 1988 when I cared for him.
One other patient I cared for was a 4 year old who had sickle cell. I took his meds in to his room for him to take, and he refused to take them. I said, Superboy, how do you expect to become as strong as your daddy if you don't take your medicine? My little Superboy said, "Superman doesn't need any pills to stay strong, and I don't either!"

Lesson one: Never ask a four year old a question if you don't want them to reduce you to about two inches in height.
